Calculating Tolerances in Manufacturing and Construction

Competency B: Communicate Ideas and Information
Task Group B3: Complete and create documents
Level: 2
At this level, learners: Use layout to determine where to make entries in simple documents

Performance Descriptors

The learner:

• May draw on additional simple sources, such as a list

To complete documents, the learner:

• Uses layout to determine where to make entries
• Begins to make some inferences to decide what information is needed, where and how to enter the information
• Makes entries using a limited range of vocabulary
• Follows instructions on documents

To create documents, the learner:

• Follows conventions to display information in simple documents (e.g. use of font, colour, shading, bulleted lists)
• Sorts entries into categories
• Displays one or two categories of information organized according to content to be presented
• Identifies parts of documents using titles, row and column headings, and labels

Task Indicators

• Scope of task is clearly defined
• Involves one document up to two pages in length
• Has a simple format
• Requires multiple entries
• May contain entry fields that are not clearly labeled
• May include unfamiliar elements (e.g. vocabulary, context, topic)
• Documents at this level may require entering a paragraph or more of text

Examples:

• Forms
• Tables
• Hand-drawn maps
• Floor plans

Competency C: Understand and Use Numbers
Task Group C3: Use measures
Level: 2
At this level, learners: Use measures to make one-step calculations

Performance Descriptors
The learner:

• Calculates using numbers expressed as whole numbers, fractions, decimals, percentages, and integers
• Calculates angles in simple, common shapes
• Makes estimates
• Understands and uses ratio and proportion
• Interprets and represents area and volume using symbols and abbreviations (e.g. m3 )
• Interprets and applies rates (e.g. km/hr, km/l) and ratios (e.g. map scales)
• Converts units of measurement within the same system and between systems
• Understands and uses formulas for finding the perimeter, area, and volume of simple, common shapes
• Chooses and performs required operation(s); may make inferences to identify required operation(s)
• Selects appropriate steps to solutions
• Interprets, represents, and converts measures using whole numbers, decimals, percentages, ratios, and simple, common fractions (e.g. ½, ¼)
• Uses strategies to check accuracy (e.g. estimating, using a calculator, repeating a calculation, using the reverse operation)

Task Descriptors

• Scope of task is clearly defined
• May include unfamiliar elements (e.g. context, content)
• Requires the use of rates or common formulas
• Requires one-step calculations, which may be repeated; operations are easily inferred
• May be completed in more than one way
• May involve one document, such as a simple conversion table
• May require converting between whole numbers, decimals, fractions, ratios, and percentages
